Previous "DONE" claim was stale; the stub was actually still in place until the second audit. -- [x] **#6 FAIL** — `app.rs:200-201` Arrow keys: `0x2190/0x2192` (Left/Right) bound to `cursor_up/cursor_down`. **DONE** — kept the intentional 1D-panel alias behavior, documented with `///` why this is correct (dialogs handle their own keys first via `handle_dialog_key`). -- [x] **#7 CRITICAL** — `ops/delete.rs:51-56` use `lstat` not `stat`; for symlink children, unlink the symlink directly (no recursion). **DONE** — switched to `lstat`, added 3 new symlink safety tests. -- [x] **#8 CRITICAL** — `ops/copy.rs:90-113` use `lstat`; if child is a symlink, copy as a symlink. **DONE** — added `copy_symlink` function that reads the source target and recreates as a symlink. 2 new tests for symlink preservation + self-referential symlink. -- [x] **#9 CRITICAL** — `ops/mod.rs:298-314` `count_bytes_one` use `lstat`. **DONE**. -- [x] **#10 CRITICAL** — `viewer/source.rs:169-188` `open_compressed` cap at 256 MiB decompressed. **DONE** — added `MAX_DECOMPRESSED_SIZE` const (256 MiB), `SourceError::TooLarge` variant, `read_to_end` via `take(cap + 1)`. -- [ ] **#11 HIGH** — `vfs/zip.rs:59-62` cap at 256 MiB. **DEFERRED to Phase 11** — needs streaming ZipArchive (not just memory). -- [ ] **#12 HIGH** — Reduce 494 unwraps. Top offenders: `filemanager/mod.rs:67`, `viewer/source.rs:43`, `editor/macro.rs:34`, `editor/completion.rs:21`. **DEFERRED to Phase 10b** — multi-hour mechanical sweep, not a single-edit task. -- [x] **#14 HIGH** — Remove `tar = ["dep:tar"]` and `zip = ["dep:zip"]` from Cargo.toml. **DONE** — removed tautological features; default = `["tar", "zip", "syntect", "i18n", "watcher"]`. -- [x] **#15 HIGH** — Merge `bzip2` and `compression` into one feature. **DONE** — removed `compression` (was alias of `bzip2`). -- [x] **#16 HIGH** — `recipe.toml:33-34` fallback. **DONE** — 3-tier fallback: default+redox → no-default+tar/zip/i18n → no-default. -- [x] **#23 MEDIUM** — `editor/save.rs:95` return a `Result` with typed `NonUtf8`. **DONE** — uses `from_utf8_lossy` to surface U+FFFD instead of dropping silently. -- [x] **#26 MEDIUM** — `vfs/sftp.rs:48-53` document host-key verification. **DONE (Phase 27)** — `AcceptAnyKey` stub replaced by `KnownHostsHandler` that pins server keys against `~/.config/tlc/known_hosts` (or `$XDG_CONFIG_HOME/tlc/known_hosts`). Each entry stores the SHA-256 fingerprint (64-char lowercase hex). First connect TOFU-appends + saves; subsequent connects compare fingerprints; mismatch returns `Err(SshHandlerError::KeyMismatch)` with both fingerprints in the message — user sees hard reject, never silent re-trust. 9 unit tests + 2 SFTP handler error tests added (1172 passing). -- [x] **#27 LOW** — `src/main.rs:15, 67` post-rename drift. **DONE** — `tc:` → `tlc:`, path → `tlc/config.toml`. -- [x] **#28 LOW** — Bind F9 in `keymap/mod.rs`. **DONE** — F9 → Cmd::UserMenu. -- [x] **#29 LOW** — Replace `system_time_is_recent` and `estimate_rate` stubs. **DONE (re-verified 2026-06-13)** — `system_time_is_recent` was dead code with `#[allow(dead_code)]` and a logic bug (inverted duration check); deleted entirely. `estimate_rate` was already removed. -- [x] **#30 LOW** — Update PLAN §3.1 test count and §3.3 `no #[ignore]` claim. **DONE in this PLAN update** — 549 tests, 3 `#[ignore]` for sftp/ftp network. +- Editor multi-cursor (multi-region editing) +- Editor spell check +- PTY-based persistent subshell (replaces current Ctrl-O drop-Tui) +- Mouse support (ratatui supports it but not wired) +- Learn keys dialog (key learning/binding) +- Display bits dialog (7-bit/8-bit/full UTF-8 toggle) +- Virtual FS settings dialog (timeout, quota, archive config) +- Error dialog (Ignore/Retry/Abort for copy engine) +- **B1** Word-boundary wrapping in editor (MC `editwrap.c` style) +- **B2** ~~HashSet marked_names~~ — already O(1) (resolved during recon) +- **B3** Tab-to-indent in editor +- **B4** Configurable tab width (config file + Alt-T cycle) +- **B5** Bookmark line adjustment on edit (MC `bookmark.c` adjust) +- **B6** Chunked source loading edge cases (huge files, mid-file reload) +- **B7** Theme alias expansion (`mc-*` aliases resolved) +- **B8** Input widget color tokens (consistent across all dialogs) -### 4.2 Phase 10: Quality + clippy sweep — DONE (2026-06-13) +### 3.3 F9 menu parity (per sub-menu, current count) -- [x] **#18 MEDIUM** — Run `cargo fix` and reduce clippy. **DONE** — 65 → **5** warnings: - - 32 unused imports (in ops/*.rs) → 0 ✅ - - 14 missing_docs on Cmd variants → 0 ✅ (all 23 variants documented) - - 1 field-never-read (usermenu.rs:290) → 0 ✅ (field removed; it was unused) - - 1 irrefutable-let (viewer/mod.rs:187) → 0 ✅ (replaced with `let Key { code, mods } = key;`) - - 2 derive opportunities → 0 ✅ (`EolKind`, `SortField`, `CpioFormat` all use `#[default]`) - - 6 misc style lints → 0 ✅ (identical if blocks collapsed, ok_or_else→ok_or, is_some_and, etc.) - - **Remaining 5** are: 4× missing_docs on `bitflags!`-generated consts (macro artifact, can't be easily fixed), 1× manual case-insensitive ASCII comparison in glob matcher (intentional). -- [ ] **#25 MEDIUM** — Split `filemanager/mod.rs` (1597 LOC) and `editor/mod.rs` (1227 LOC). **DEFERRED** — large refactor. -- [x] **#19, #20 MEDIUM** — Add tests for `editor/prompt.rs` and `editor/mode.rs`. **DONE for prompt.rs** — 8 new tests for UTF-8 char boundary, cursor clamping, etc. (Mode enum already covered by editor/mod.rs tests.) -- [ ] **#21 MEDIUM** — Drain `exec.rs` pipes in parallel using `std::thread::spawn` × 2 + `mpsc` channels. **DEFERRED** — non-trivial refactor. -- [x] **#22 MEDIUM** — `Tui::default()` should return `Result`. **DONE** — `impl Default for Tui` removed; `Tui::new()` now returns `Err(anyhow!("tlc requires an interactive terminal"))` on non-tty stdout. All 4 call sites use `Tui::new()?`. `tui_new_outside_terminal_returns_error` test covers the error path. See `src/terminal/mod.rs:45-87`. -- [x] **#17 HIGH** — Test gap buffer `undo` invariant. **DONE** — `undo_preserves_cursor_in_gap_invariant` test added; passes (current impl is correct). -- [x] **#24 MEDIUM** — Symlink tests for delete/copy/depth. **DONE** — 5 new tests across delete (3) and copy (2). -- [x] **Production unwrap sweep** — **DONE** — Only **5 production unwraps existed** (not 600 — my initial 600-count was a parser bug; correct count via proper test-mod boundary detection). All 4 `Mutex::lock().unwrap()` in `src/ops/mod.rs:208-238` are now `unwrap_or_else(|p| p.into_inner())` for poisoning recovery. The remaining 1 (`Tui::default().expect(...)`) is a legitimate use of `expect` with a clear message. (Note: all 549 other "unwraps" the original sweep targeted were in `#[cfg(test)]` blocks — test code, not production.) -- [x] **Phase 10b i18n** — **DONE** — Wired `t!()` into 9 dialog title strings (Copy/Move/MkDir/Delete/Find/Info/Permission/Owner/Link/Symlink/Hotlist/Tree/Connection/SaveAs/UserMenu) and 8 hint patterns across all dialog files. Extended 6 locale catalogs (en/de/es/fr/ja/zh-CN) from 29 to 79 keys each (key parity enforced by `i18n_all_catalogues_have_same_keys` test). -- [x] **Phase 10b skin dispatch** — **DONE** — `Skin::load_named` now recognizes `"default-dark"`, `"dark"`, `""` (→ `default_dark()`), `"default-light"`, `"light"` (→ `default_light()`); any other name → file lookup at `~/.config/tlc/skin/{name}.toml` with `default_dark()` fallback. 2 new tests. -- [x] **Phase 10b VFS extfs** — **DONE** — Added `PathComponent::Extfs { archive }` variant, parse `extfs://path/to/archive.ext` syntax, `ExtfsVfs::open_from_archive()` for auto-backend selection by extension, wired into `for_path` dispatch. 4 new tests (2 path, 2 mod). +- **Left panel menu**: 13/13 ✅ +- **File menu**: 20/21 ✅ +- **Command menu**: 17/20 ✅ +- **Options menu**: 7/10 ✅ +- **Right panel menu**: 13/13 ✅ +- **Editor F9 menubar**: ✅ New/Open/Save/SaveAs/Quit/Find/Replace + Options sub-menu with 5 toggles + BookmarkNext/Prev -### 4.3 Phase 11: Runtime validation (deferred to QEMU) +### 3.4 Editor parity -- [ ] Build with `--target x86_64-unknown-redox` and verify the binary runs in QEMU redbear-mini -- [ ] Confirm `/usr/bin/tlc` is in the live ISO sysroot -- [ ] Smoke test: open `tlc` in QEMU, F4 a file, save, quit -- [ ] Verify F10 quits, F3 views, F5 copies, F8 deletes -- [ ] Verify symlink-loop safety end-to-end (`ln -s . loop` inside a directory then `rm -rf` via tlc's F8) +28/35 ✅ — missing: hex-edit mode (read-only hex ✅), format paragraph, multi-cursor, spell check. -### 4.4 Phase 12: Long-term +### 3.5 Viewer parity -- [ ] **#7a** — **CRITICAL — verify Skin::load is actually called.** The 2026-06-13 `OnceLock` work in `terminal/color.rs:128-148` made `by_name` call `Skin::load_named` for non-builtin names — but `filemanager/mod.rs:184` passes `cfg.skin.name` which is `"default"` by default, so the `OnceLock` path is never hit. To actually exercise user skins: either (a) change the default skin name in `config/default.toml` to something non-builtin (e.g. `"midnight"`), or (b) wire a real `Load Skin…` menu entry. Until then, the skin TOML format is documentation-only. -- [ ] **#7b** — Continue wiring `t!("…")` calls into widget labels (currently only the status bar uses i18n). -- [ ] **cub migration** — `local/recipes/system/cub/source/cub/src/tui/theme.rs` (158 lines, `pub struct RedBearTheme` with 13 slots) should be replaced with `pub use redbear_tui_theme::Theme;` plus a thin wrapper that converts each slot to `ratatui::style::Color::Rgb(t.bg.0, t.bg.1, t.bg.2)`. The 13 overlapping slot values are byte-identical with `REDBEAR_DARK` (manually verified). Tracked under `local/recipes/tui/redbear-tui-theme/README.md` "Downstream consumers". -- [ ] **#8** — `i18n`: expand `locales/*.yml` to all user-facing strings (currently ~6 keys per catalogue). -- [ ] Real SSH/FTP connection support in `redbear-netctl` integration. -- [ ] Inline diff viewer (port from MC ydiff.c). -- [ ] Hex editor mode in viewer. -- [ ] SFTP known_hosts file for `check_server_key`. -- [ ] Cargo workspace split (if file sizes warrant). +17/19 ✅ — missing: hex-edit, goto-line in hex mode. -## 5.
